MISTM impactor is powered by mud motor, which can create and transmit high frequent impact force. MISTM impactor can induce the BHA to make benign vibration, overcome drag and friction, rotate and break the rock through impact force, thereof improve ROP.
Features:
1) No negative influence on the MWD systems.
2) Applicable for all kinds of drilling fluid, including air and Nitrogen system (Multiphase flow system)
3) No limitation to the pump rate.
4) No need for Impact bit, no effect on the bit milling.
5) Efficient WOB transmission to the bit.
6) Impact force can be adjusted according to the compressive strength of rock being drilled.
7) Inducing BHA stimulation, conducive to drill the highly-deviated well and horizontal section.
8) No influence on the passing of LCM material and high solid content fluid.
